What playlist are you in? Lately there has been under 100,000 people online. Some playlists have very few people in them. I play the Apocalypse playlist and there has been less than 600 at times playing TDM. If that's not the case just wait a minute or 2 before trying to find a new match.

For example in League Play there are around a total of 800 players across the world at any given time. That makes 8 seperate maps lists for each "map collection" that players have . So right there that cuts it down to about 100 people who have the maps that you have.

So across the world you have 100 players to choose from where 80 percent of those are already in a round. Leaving around 20 people to join up with.
